Application filed September 16,1918. SerialNo. 254,354;

To all whomit mag concern:

Be it known that we, EDGAR B. ULLMAN,

EUGENE l3. S rMoNns, and ARTHUR F. AT-

KINSON, citizensof the Unitedcbtates, residingat Muncie, Delaware county, and State of Indiana, have invented and discovered certain new and useful Improvements in l-Ieat and Vapor Bath Cabinets, of which tained without the creation- 0f fumes or' gas from the heating apphance, and n which the heat generated is efiiectively utilized to its fullest extent; in whlch the heating medium is provided by a self contained electric unit which may be readily moved and easily disconnected fromthe body of the cabinet, and whereby means for supplying vapor to thecabinet and means for heating the interior thereof with dry heat may be connected to separate heating units so that either of said means may be em- ,ployedseparately, or both in conjunction.

Vith these objects in View, our invention is BIHbOCilBCl 1n preferable form ln'the construction and arrangement hereinafter described and illustrated in the accompanying drawings. 3 '1 i In these drawings, .Figure 1 is a perspective view in elevation ofthe cabinet body;

Fig-a verticallongitudinal section, and

Fig. .3, a horizontalsection, and Fig.4, a detail vertical section of the steam generator. 7

Referring to the drawings, l indicat'es the cabinet which is of a form andsize adapted to receive". the body of a person when stretched at full length and which is adapted to be closely sealecland is provided at one end thereof withian opening 2, through which the head of the patient is projected and which opening is adapted to be closed preliminary to the treatment by means of a hinged door 3, adapted to fold down upon a bracket 4- in order to constitute a head rest. The cabinet is provided with a hinged lid 5 having a beveled upper surface. Legs 6 are provided at the corners of the cabinet for holding the same elevated above the floor. The bottom of the cabinet is made of sheet metal and slopes slightly from the ends andsides toward the center thereof Specification of Letters IlPatent.

where it is tappedto receive a drain pipe I 7; Mounted above the bottom is a slatted body support .or bed 8 which is preferably ucurved downwardly toward the center of the cabinet from each longitudinal side border thereot One side ofthe cabinet is divided and hinged to permit the ready entrance of the patient.

Between thesupporting bed the bottom offthecabinet extends a coil -or. frame of heating pipesefi, 10, 11 and 12,! which are connected, andwvhich at oneend communicate with anyinlet pipe 13, 1 and .at thefiother end communicate with anoutlet 14; open to the atmosphere. These pipesare adapted to receive steam and are adapted to, raise the temperature of. the air and vapor within the cabinet to the desired point by radiation therefrom; To this end the inlet pipe is connected'to a steam generator comprising a sheetmetal water container .or tank 15, by means of aninter mediate pipe 16 having a slip joint at the point ofconnection with the radiating pipes.

This member constitutes aself contained steamgenerator,and to this end it is provided, with an electrical heating "unit 17 immersed. inthe water with which the tank is adapted to be supplied, and whichdevicemay be ofa'ny standard immersed electric heating unit. This-heating unit is prowided at its lower end with a tube or pipe section 18xwhich is. threadedinto the bottom" of thecontainer and through. which pipe the'conductor wires 19 leadingsfroln a suitable source of electrical energy to the resistance elements of the heating unit are passed. Leading into the bottom of the tank of the generatoris a filling and indicating pipe. 20, which extends upwardly exterior of the tank and terminates at its upper end, substantially at the level of the water in the generator, andwwhich endis open or adapted to be closed by a readily removable cap so that the corresponding height of the water in the generator may be determined from an inspection of the level of the water in this filling pipe.

The tank of the steam generator is pro vided with a slip cover 21 adapted to fit within the upper end of the tank and having an exterior rounded top. Within this top is provided a conical false top or plate 22 adapted to form a dead air space between the same and the outer curved top, and to form within the same a steam confining and directing chamber 23, the shape and area of which contribute to the ready generation of the steam'within the tank and which serves to direct the steam to the central part thereof where the cover is connected to an elbow of the connecting pipe 16. By this arrangement a confined steam space is provided above the water in the tank and the generation thus facilitated, and the same properly directed to the conveying pipe.

Mounted within the cabinet, preferably between the section of the radiating pipes, is a vapor conveying pipe 24 which pipe is perforated throughout that portion thereof which lies within the cabinet in order to per- 'mit the escape of the vapor to the interior of the latter.

This pipe communicates with a generator unit adapted to contain sulfur and water, or suitable medicaments adapted to the treatment which may be applied in particular cases, and such generator consists of a container 25 and electrically immersed heating unit 26, both similar to the corresponding elements described in respect to the self with the heat usually generated by a gas burner, and in which constructions a separate furnace and separate boiler are required. In these constructions, or those of similar type, frequently the fumes and gas escape into the cabinet to the detriment of the therapeutic treatment, and also the presence of the fumes and gas in the room occuied by the cabinet is highly objectionable. loreover, such constructions usually require separate heat and steam generating units and are not readily portable and separable. In devices of this class it is highly important not only that a pure condition of the air be maintained in a surrounding cabinet, but also that the heating unit be capable of being readily handled, moved and attached to or detached from the cabinet. This result is accomplished in our invention by providing a self contained steam generator comprising a liquid containing tank and the electricalimmersed heat unit which as an entirety may be readily lifted and which owing to the slip connections with the cabinet may be readily detached therefrom andmoved from place to place, and in which the heat within the cabinet is produced solely by the radiation from the steam pipes in conjunction, when desired, with such heat as may be provided by the medicated vapor through the central pipe.

Having thus described our invention, what we claim is 1. In an applicator a vapor generator and heater comprising a receptacle, a compartment formed within the receptacle with communication established between such compartment and the under side of the receptacle, a heating unit disposed within the compartment, and a conduit leading from the receptacle to the applicator.

2. In an applicator a vapor generator and heater comprising a receptacle, a compart ment erected within the receptacle and closed wholly upon those surfaces located within the receptacle but communicating through the bottom of the receptacle, a heating unit located within the compartment, energizing means for the heating unit extending through the opening in the bottom, and a conduit leading from the receptacle to the applicator.

' 3. In an applicator a vapor generator and heater comprising a receptacle, a heating unit erected within the receptacle and having an outlet only through the bottom of the receptacle, energizing conductors leading into the compartment through the opening in the bottom, a heat insulating cover member positioned over the top of the receptacle, a conduit forming communication between the receptacle and the applicator, and means to introduce water into the receptacle without removing the insulating cover.

In witness whereof we have hereunto set our hands and seals at Muncie this 9 day of September, A. D., nineteen hundred and eighteen.
